Set oven temperature to 338 °F.
Mix the dry ingredients using a fork or whisk.
Cut butter into 1tbl chunks. Then, using your hands, rub the cold butter into the dry ingredients, then work in the rose water.
Knead for 10 minutes until it forms a smooth dough.
Gather the dough into a ball. I cut the ball it in half to make it a little easier to roll out, but you can also do it all at once if you prefer.
Roll dough out to 1/4 inch thick on a floured surface. I found that placing a piece of plastic wrap over the dough makes it much easier to roll. The dough doesn't come apart with plastic wrap over the top. Cut dough into 3 to 4 inch rounds and then place them on a baking sheet.
Bake for 15 minutes, until they are just starting to change color but not browned. These are a pale cake/cookie!
Remove from the oven and sprinkle caster sugar over the top of the cookies.
Stack cookies in columns and leave to cool. The column is important because of the amount of butter in the dough!
Enjoy with a cup of tea or on their own!
